# Check for Element in List

Search is performed through the list to determine whether the sought element is contained in the list or not.

<table data-header-hidden><thead><tr><th width="239" valign="top"></th><th width="320" valign="top"></th></tr></thead><tbody><tr><td valign="top">List</td><td valign="top">[List] The list in which to check for the presence of the sought element.</td></tr><tr><td valign="top">Element</td><td valign="top">[Text/Number] The element whose presence needs to be verified.</td></tr><tr><td valign="top">Whole Word</td><td valign="top"><p>Word boundaries will be considered during the search.</p><p>For example, with the property enabled, the value "Value" will be found in the text "This Value", but will not be found in the text "This ValueTest".
