Hi NH-09100837-0,

To achieve this, you can make use of the Switch statement in the DefaultSelectedItems property of the second dropdown.

Items property of the First Dropdown:

["A", "B", "C", "D"]

Items property of the second Dropdown:

["E", "F", "G", "H"]

Here is the DefaultSelectedItems property of the Second Dropdown:

Switch( firstdrpdown.Selected.Value, "A", ["E"], "B", ["F"], "C", ["G"], "D", ["H"] )

Here's how it looks:

Hope this helps.

Kind regards,

Nandit

using the Switch function in Power Fx, We Can Achive this

Set the Items property of the second dropdown based on the first dropdown selection:

In the OnChange property of the first dropdown (let’s call it Dropdown1):

Switch( Dropdown1.Selected.Value, "A", "E", "B", "F", "C", "G", "D", "H", "" )

Set the Items property of the second dropdown (let’s call it Dropdown2) to this formula:

Table({Value: Switch(Dropdown1.Selected.Value, "A", "E", "B", "F", "C", "G", "D", "H")})
