Combobox values not appearing in Pop up Page
Hi,
Please refer the below mentioned code part and guide us to the solution.
Parent Page:
Pop up Window
.aspx page
After the page load for the first time, the drop down shows only 7 items and the remaining records gets hidden as it doesn't show the Vertical Scroll bar.
Steps to reproduce:
1) Click on Pop it link
2) A pop up window opens. In that select Excel from the first drop down.
3) Click on the second drop down, it shows only less values without vertical scroll bar.
Refer to the screen shot.
Please refer the below mentioned code part and guide us to the solution.
