title: Google Sheets custom sidebar: How to display a current cell value in sidebar without reload the sidebar?
body: <p>I have a list of fruits name in a sheet. Then I made a custom sidebar that will show an information of a selected name by selecting a cell in a sheet without reloading the sidebar or without clicking any button in the sidebar. Only just select a cell. Is it possible? And How can I do it? Thank you in advance</p>
