Using Text Box In a Split Pane

I have added a Form to the Side Pane (IonInput, IonSelect etc). It works when the side pane is expanded. But when side pane is collapsed and overlays on teh main content, the text boxes become disabled. Only Buttons are enabled.

It looks like there is a CSS that controls. CAn somebody help with a CSS that allows me to have the form controls enabled even when the sidebar is in overlay mode?
