How to Add an 'Other' Input Box for a Select Dropdown Field

Can I add an input box that appears when the 'Other' option is selected in a Select dropdown field?

Yes, in Dryfta you can create a dependent input box field linked to the 'Other' option of your custom Select dropdown field. 

First, create your dropdown field with various options including 'Other'. 

Then create a separate input box field and set it as a dependent field connected specifically to the 'Other' option of the dropdown. See this screenshot: https://gyazo.com/a58677e2ba3034392927f5d0b86fd97b

This way, when a user selects 'Other', the input box appears for them to enter a custom response.
