Hi DeepakS2275,

So, your data grid can grow but not the three categories. However, you want to stretch your category headers with the grid columns.

I am doubt though they auto stretch, are the columns you want to show in specific category fall into the specific header region?, Definitely not, isn't it?

If I were you, I will go with following approach.

I use, Inline grid triple dynamic layout and use each column of the dynamic layout for a category

I choose, row 1 to display category headers. "structure", "requirements" and "actions"

I choose, row 2 to display a grid for each category. This way you have three grids and will add columns for each grid.

I choose configuration of fixed width grid. This way, If grid grows horizontally, I would expect to see scroll bar for the grid but not for the header. I will mimic the skin to make it appear like single grid.

Limitations :

 This configuration would be not great for mobile application

We've new templatized grids introduced in pega infinity, this grids can be used to show or off the columns, user can have their own copy of display and many more features for runtime edit, Please have a look.

Yet, you can post your questions and concerns, happy to answer them.

Thank you,

Regards, Cherb.
