Hi,

 Yes, it's possible. Two ways:
 1 - Insert one blank child row to the row within the Toggle, them 
connect the "before expand" signal to a callback function where you 
verify if toggled. Them, if toggled, you delete this blank row and 
insert new rows.
 2 - When inserting, you verify if toggled, if yes, you insert children 
rows, if no, not insert. Then you connect the "toggled" signal to a 
callback function where you check if toggled, if yes, you insert 
children rows, if no, delete children rows.

I prefer the second option, but the first option provides insert rows 
just only the user see children rows. You can also mix the options.

 Good Luck!
