# If Control under which circumstances an Action Node or a set of nodes should be executed. You may add conditions to the `IF` node, and you may add Action Nodes as children of the `IF` node. If the condition is evaluated as `true`, all Action Nodes inside will trigger. You may also add `IF` nodes inside another `IF` node, for more complex evaluation or control of the Action flow. The If action node requires only a Condition to be set up. * Data Binding: Select a property (must be a boolean type property) holding TRUE or FALSE. The If will evaluate to TRUE depending on the property you select for Data Binding. * Condition: Use the [Condition Editor](/reference/platform-concepts/conditions.md) to set up a logical expression. The If will evaluate to TRUE is this expression evaluates to TRUE. * Function: Use the [Function Editor](/reference/platform-concepts/functions.md) to set up an advanced expression. You may use Javascript inside the Function Editor. The function must return either TRUE or FALSE. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
