How to Add the Sub-Select Field to Your Form

We are currently waiting for JotForm to add the new On2Air: Forms widget to their Integrations area. This does not affect the features of On2Air: Forms, however, you will currently need to configure your fields in our dashboard instead of in the JotForm builder. To set up your form, please jump to this section >>> Use the On2Air dashboard to add new On2Air fields to your JotForm form. The process documented below will be the process for adding fields to your forms once JotForm adds the On2Air widget to the Integration area.

Select the Display field

Add ?cities=<searchvalue>|1 OR ?city=<searchvalue>|1 to the end of your form URL

Only certain cities will display depending on their checkbox status when your form is loaded

Airtable View

Final URL Styling<searchvalue>|1

Case Sensitive - Toggle On for Case Sensitivity - Off by default

Default Value - A specific hard-coded value to display as the default pre-filled value in dropdown. The value must match an option listed in your Initial Field selected above.
If you have a parameter in your Initial Field, it will take priority over the Default Value field.

This ensures your user can't delete the URL parameter for a workaround in your form. If there is no filter in your URL and this feature is On, the search filter will not work. See example above using URL parameter.

Advanced Feature

Filter - Create custom formulas to further filter results
Contains Helper properties of SEARCH_VALUE and DYNAMIC_VALUE are included.
SEARCH_VALUE can be used as a placeholder for any user-typed value in the field. Anything returned ‘True’ in the formula will be displayed in the results.
DYNAMIC_VALUE will give whatever you used as a URL parameter

Advanced Display Configuration

If the display count amount is lower than the number of field record options, the form user will need to continue typing out the search term until the desired record is displayed

Hidden - Enable this to hide the field

Disabled - Makes a field disabled. Only use if the Initial Value field is configured since it sets a default pre-filled value

Searchable - Determines whether the field should be searchable

Clearable - When a selection is made in your dropdown, an X will display for the user to clear the field

Close on Select - Once a selection is made, the dropdown will automatically close

Disable Resize - When the select opens or shuts, it resizes the area around it to make room. This can cause issues, especially on mobile iPhones. This will disable the resize but force a large enough area for the dropdown

Use pixels - Should be a numeric value

Maximum Height for Results - Maximum height of results selection
Use pixels - Should be a numeric value
