What you'll build
By the end of this guide, you'll have a form field that lets respondents search a list of choices and select more than one, with their picks shown as removable chips. You'll set minimum and maximum selection limits, customize the validation messages, and see how those selections flow into answer piping, the data block, and your integrations.
When to use this
Your option list is long, and a standard Multi choice field turns into a wall of checkboxes respondents have to scroll through
You need people to pick more than one item, so a regular Dropdown field won't work
Respondents keep asking for a way to search instead of scanning a long list of choices
You want selections to appear as clean, removable chips instead of a stack of checked boxes
You need to cap how many options someone can pick, like "choose up to 3 services"
Adding the field in the form editor
Multi-select Dropdown lives in the Choice section of the Add field panel, right after the standard Dropdown field. Dropping it onto your canvas doesn't introduce any new editor behavior, it looks and drops in exactly like every other field, so there's nothing new to learn before you get into configuring it.
1. Open the Add field panel: In your form editor, click Add field and go to the Choice section. You'll find Multi-select Dropdown listed right after Dropdown.
2. Add the field to your form: Click Multi-select Dropdown to drop it onto the canvas. It renders the same way a standard Dropdown field does, so respondents will recognize the interaction right away.
3. Publish your form: Once you've configured the field using the settings below, click Publish in the island bar at the top of the editor to make it live.
Field settings
The settings sidebar follows the same layout used across every field type: a Field section, a Settings section, an Insert section, and a Translate & Customize section. Most of what's specific to Multi-select Dropdown lives in Settings, alongside a couple of controls that don't exist on a regular Dropdown field.
Field type, ID, and visibility: the top section shows the field type, an editable field ID, and toggles for Required, Admin-only, and Invisible, the same controls every field type has.
Choices: add, edit, reorder, or delete options using the same choice editor as the Dropdown field.
Default answers: pre-select one or more choices for respondents, the same multi-select behavior as a Multi choice field.
Shuffle choices: toggle this on to randomize the option order for each respondent, useful for reducing order bias in surveys.
Min. selectable options: the fewest choices a respondent must select before submitting.
Max. selectable options: the most choices a respondent is allowed to select. Leave either min or max blank to leave it unrestricted.
Insert: use the bulk insert box to paste your entire option list at once instead of adding choices one by one, identical to every other choice field.
Translate & Customize: edit the field's text strings here, including the placeholder ("Click to select" by default), the searching and no-options-found states, and the two validation messages for minimum and maximum selections. These support translation if your form runs in multiple languages.
Note: Setting Max. selectable options to 1 turns this into the equivalent of a single-select Dropdown, which is a valid setup if you want the search UI without allowing multiple picks. An "Other" option and reservation or availability limits aren't available for this field.
Form view
Respondents interact with Multi-select Dropdown the way they would with any searchable autocomplete field. Nothing looks selected at first, but the moment they start picking, the field organizes itself so they always know what they've already chosen versus what's still on the table.
Before selecting anything, the field shows your placeholder text (by default, "Click to select") inside an empty trigger.
Clicking the trigger opens a dropdown with a search input at the top, with every choice listed as a plain row underneath.
Once at least one choice is picked, the dropdown reorganizes into two labeled sections: a Selected options section at the top, listing everything the respondent has already chosen, and an All options section below it, listing everything still available to pick.
Typing in the search bar filters both the Selected options and All options sections in real time, so long lists stay easy to narrow down.
Each selected choice also appears as a chip inside the trigger itself, sitting right where the placeholder text used to be, with its own × button attached.
Removing a selection works from either place: clicking × on a chip in the trigger, or clicking × on a row inside the Selected options section, deselects it immediately.
Validation kicks in on submit. Going below your minimum shows the min_error message inline. Trying to go past your maximum blocks the selection outright and shows the max_error message before the respondent can add another choice.
Choices stay plain and uncolored throughout form view, no matter how many colors you've assigned in the data block. Color is strictly a data block concept, and the form view experience is identical on desktop and mobile.
Logic
Multi-select Dropdown works as both a source and a target for conditional logic rules, the same way Multi choice does. That means you can trigger a rule off what someone picks, or use logic to assign a value into this field automatically.
Supported trigger conditions are is, is not, and is answered.
Only one option can be set as the trigger value at a time, even though the field itself allows multiple selections.

Answer piping
Multi-select Dropdown supports answer piping just like every other field, so you can pull whatever a respondent picked straight into an email, a PDF, or another field further down the form.
The piped output is a dash-separated string of the selected labels, in the order the respondent picked them, for example:
Minimal & Clean - Dark Mode / Sleek - Vibrant & Colorful.If nothing was selected, the piped value is empty, nothing is stored and nothing renders.
The field's ID shows up in the @ piping menu everywhere piping is supported, including the form editor, the Email Editor, and the PDF Editor.

Data block and filters
Once responses start coming in, this field shows up in your data block the same way Multi choice does, just with the added ability to search and cap selections on the way in. Here's what changes between the form and the data block, and what stays the same.
How responses render: each selected choice shows up as its own colored pill chip inside the response row, using the same pill UI you already see on Multi choice fields. Colors are assigned in your data block settings, there's no separate setup for this field.
How filtering works: clicking any pill filters the table down to only the records that included that choice. You can click multiple pills to combine filters, and the underlying logic matches Multi choice filtering exactly, so nothing behaves differently just because respondents searched to find their answer.
What isn't supported: sorting by this field and grouping by it in a Kanban board. Both are unavailable because a multi-value field doesn't map cleanly to one sort position or one Kanban column.
How it charts: the field's chart is a bar chart showing how many times each option was picked across all responses, the same chart type Multi choice already uses.

Export and integrations
Multi-select Dropdown is built to behave identically to Multi choice everywhere its data leaves Formaloo, whether that's a spreadsheet, an import, or a third-party tool. You shouldn't need to change anything downstream just because you switched field types.
CSV and Excel export: selected choices export as a dash-separated string, the exact same format as the answer piping output.
Import: supported, using that same dash-separated format to map selections back into the field.
Renaming a choice after responses exist: the new label reflects everywhere, including on existing responses that already had it selected.
Deleting a choice after responses exist: it's removed from every existing response that had it selected, along with everywhere else it appeared.
What you now have
You now have a compact, searchable way for respondents to choose multiple options without scrolling through a long checkbox list. Selections are validated against your min and max limits, flow cleanly into emails, PDFs, and exports as a dash-separated string, and show up in your data block as filterable, colored pill chips. It's a small field-level change that removes a real workaround your team and your respondents no longer have to think about.
