In the angular kendo-grid I have, each column has an ellipses menu that shows sort options and a menu for choosing the columns that are displayed. Some columns are shown, some are hidden, and these can be toggled with a checkbox. How can I put this checkbox menu chooser inside it's own pop up on the same page as the grid? The goal is for a button to show the pop up menu (underneath the button) that shows only this checkbox list of columns. The user can click the button and choose the columns, and update the grid. The ellipses menu functionality would be the same.
