Hi All,

Requirement : I have a table where the last column is a text area where user can enter some free text which can be more than 2 lines. But to have a better user experience we taught of opening a pop up on clicking of text area with a free text area and upon submission it should simply update it in the table text area column.

I broke this task into below subtasks

1. OnClick event open a dialog box -> No issues

2. In the dialog box have a text area which is large enough -> No issues
