DropDown & MultiSelect Field
The Drop-Down Field allows you to select an option from a list of data. The Multi-Select field works similarly to the drop-down field, but it allows you to select more than one option from the list.
Properties
When you open the Properties, you'll find a few things to fill in. First, give your drop-down a name with the Field Title. Then, set a unique code for it using the Field ID. Choose where your options come from with Data Source. Lastly, make sure everything is correct by using Validation checks.
Field Setting
See Basic Field Settings like Title, ID etc. Here
Data Source
In the Data Source section, you choose where your options come from. By default, it's set to Custom List, meaning you create your own choices. You can also switch to DataSet, where you pick options from existing data.
Custom List
When you choose Custom List as the Data Source, you can create your own options. Type each option in the input field, and press the plus button to add it to the list. This way, your drop-down will have choices that you specifically enter. Each added option comes with a minus button, allowing you to delete it from the list if needed.
Dataset
If you choose DataSet as the Data Source, you have two drop-downs to set up. First, pick your source dataset from the Source drop-down. Then, choose a field title from the Field Title drop-down. This way, your drop-down will be filled with the fields of the selected dataset.
Search List
The Search Field feature allows you to search for data while working in the form.
You can use the filter to search within your data, but the filter will only display the fields that you have selected.
Clikcing the plus button will select this data for the field.
Filter Option
Click on "Filter" in the drop-down menu to manage your filters. This opens the filter page where you can easily view, adjust, and customize your applied filters.
Explore your filters on the Filter Page for more detailed control.
