Customize Popup Width

14 Dec 20243 minutes to read

The PopupWidth property determines the width of the dropdown popup in the DropDownButton component. By default, the popup’s width adjusts based on the content. However, this property allows setting a specific width, ensuring consistency and alignment with design requirements. The width can be specified using common CSS units or as a raw pixel value.

CSHTML
