multiple forms in the same container or panel

Is it possible to have more than one form in the same container (for example, the default container)?

The first form has a list and a button. User select a layer to search from the list, then click on the Search button.

After the Search button is click on the first form, the second form appears under the first form in the same container/panel. The second form allows user to put in search criteria.

After user  click Search button on the second form, the search results appears in the same container under the second form.

I attached a picture of the forms below.

Is it possible to achieve this?  Thank you.
