[to be closed] InputField inside a Horizontal Layout Group

Dear Unity users,

I'm having trouble using the UI auto layout system along with the InputField element.

Here is what I wanted: a UI text element with a button to activate/deactivate the edition of a field. (for example, a name)

Here is what I did:
Create a panel named 'NameEdit', add a horizontal layout group component, set Child Force Expand Width to false
Create an InputField child of the panel 'NameEdit', add a layout element component, set flexible width to 1
Create a button child of the panel 'NameEdit', add a layout element component, set flexible width to 0

Try the UI in the player, the text inside the Input field is not showing.
If I delete the button and the layout element component, and if i set Child Force Expand Width to true, it doesn't fix anything
So, it appears that putting an InputField inside a horizontal group seems to break the text display of the InputField.
Can anyone tell me what am I doing wrong here?

Thanks in advance!

EDIT: Ok my bad, I posted this issue since I struggled for hours, but it seems that the text disappeared because of the insufficient vertical size of the rect. And every single test I did, the vertical size of this rect wasn't enough, and I didn't notice. I should have waited some more before posting this!
