Icon to indicate 'drop down' on the Advertise page

I have a suggestion for the development team.

In the plans section: - (List With US page or the “Advertise’ page)

For the product dropdown, instead of an ‘'X" to indicate ‘click here’, a Down Arrow should be used.

…. which turns into an "X" after the plan is dropped down.

When a user wishes to close the dropdown, they click on the "X".

After the dropdown closes, the icon returns to being a down arrow.
