How to set the Fill property of a combobox if the drop-down is selected?

Question

Can anyone help me to change the Fill property of a ComboBox when the ComboBox is selected by the user? Currently, when the drop-down is clicked the values to be selected are transparent across the other values in the gallery. I'd like to set the fill property to white on drop-down so the selectable options are clearly visible. Thank you!

I've tried to use ".IsSelected" and ".Selected" but to no avail.

You have properties like below for Combo box control in Power Apps:

• SelectionColor
• SelectionFill
• SelectionTagColor
• SelectionTagFill
• Fill

You might want to utilize those properties based on your requirements.

Here are some Accessibility guidelines for combo box control

Anyway, if you want to set color conditionally, you can use formula in this format:

If(
    IsBlankOrError(dropdownControl.Selected),
    RGBA(0, 0, 0, 1), // Some other color as per your requirements
    RGBA(255, 255, 255, 1) // White
)

If the value is selected in drop down, it will show the white color else other color you specified.
