Hello @Lalo,

i need to be able to resize the columns in my form to fit the height and width when the user wants to

The resizer handle cannot be used to adjust the width of a single component (that’s how it currently is in your example, which is why your example is not working). You will need to make some adjustments to the overall layout, but the end result look something like this: https://snippet.webix.com/yb4ike00. Please note that the handle is now placed in-between the two main columns of the form.

I thank you for the help, it worked finally
