Action: Enable and Disable

Use an enable/disable rule to make a field editable based on one or more conditions.

Example: Part of the race registration fee pays for dog food. You don’t have to feed your chicken team with the provided dog food though. There’s a single selection field that asks Would you like use the provided dog food?. If you select Yes, you can select how much food, in US pounds, you’ll need for your team throughout the race. Since you’re racing chickens, you’ll select No, and the Amount (US lb.) field is disabled.

To follow the example, add a single selection field Would you like to use the provided dog food? with two options: Yes and No.

Add a numeric field called Amount (US lb.) and make it an Integer. Use field validation to make sure it’s not greater than 100.

To set up the enable/disable rule,

1. Open the Rules tab of the Edit Form page and click the Add () button.

2. Define the rule:

   • If the Would you like to use the provided dog food? field is equal to Yes, enable the Amount (US lb.) field.

   

   Figure 1: Build form rules quickly by defining your conditions and actions.

   • Save the rule.

   

   Figure 2: Once a rule is saved, it is displayed so that you can easily understand what it does.

Now users can fill out the amount of dog food they’ll need only if they specify that they do indeed want to use the provided food.
