The example in this article describes how jquery implements the pull-down effect of a selected radio button. Share it with everyone for your reference. The details are as follows:

This is a telescopic effect achieved using jQuery plug-in. On the web page, after clicking the radio button, that is, the Radio element, the corresponding content will be pulled down and stretched out. It is not usually displayed. It can be used in Invoice printing, express delivery order inquiry and other occasions.

The operation effect is as shown below:

The specific code is as follows:
