hi, Currently I am working out a code which displays products that appears in three levels , level1 (parent level), level2 (child level),and level 3 (grand child level). I am implementing it as flexigrid. as such the flexigrid is working fine. I am having a combobox control with with two options - Expand and Collapse . On selecting the Expand option of Combobox , all the three level product items are getting displayed. But on selecting the Collapse option I am required to display the only the level 1 product items, But I am getting the the products in expanded state itself with all three level products. how am i required to modify the code to display the level 1 items .? can any one help me in solving this ?
