title: Ag-Grid expand row
body: <p>Im using Ag-grid to control my table, but i want in my group that stores a list of  rows instead of having to make the row group expand in 2 clicks, i want to be on 1 click. 
  If i click on the icon arrow it works, but if i click on the title row it only opens on 2 clicks.</p>
  
  <p>I already tried to find in the documentation any information about it, but cant find nothing.</p>
  
  <p>Here is a example from the documentation.
