Show a Question Only When It Matters

Put questions inside show when to show them only while another question has a certain answer. The user never sees questions that don't apply to them.

In this example, Tap the Arena button only shows when the user picks Arena:

Conditions

Set id to the checkbox, options or dropdown to watch, then choose:

Choice	Shows the questions inside while...	Lua
checked	the checkbox is ticked	showWhen(id)
not checked	the checkbox is not ticked	hideWhen(id)
option id	that option is chosen	showWhen(id, optionId)
not option id	any other option is chosen	hideWhen(id, optionId)

Good to know

• A hidden question never stops OK, even if it must be answered. A user who picks Farm never has to show you the Arena button.
• A hidden question keeps its last answer. Only read its answer when the condition holds.
• show when works around pages and sections too, to show a whole page or section.
• If the watched checkbox or choice is hidden itself, the questions that depend on it hide too.
