Add an overflow: visible; try
Add an overflow :visible; Try
What effect do you want to achieve

After some research, it turns out that you cannot simply use min-height, otherwise the action will be unnatural. You can use jquery to traverse the height of the pop-up layer. If the height is less than a certain value, just The height of this pop-up layer is set to a certain height. In the example I made, it was set to a minimum height of 300px in js
In addition, I have to admire the courage of the person upstairs to add overflow: visible. I am really impressed. . . Ha

Thank you very much, but
You can't do this! ! ! When the content is higher than 300, the frame will not be automatically extended! ! IE8 is not compatible with Firefox
I tested it and it can be automatically extended. I also tested it on Firefox and it was OK. As for IE8, it is not installed on the computer, but it should be OK.
The first sub-column of the column in the source file below is automatically extended,
