On the left-side panel of the background, how can I keep the left-side panel when I click to jump to the new page? Thinkphp3.2 unclear
What you want to achieve is

For example, click in the top navigation bar to display the corresponding left panel (implemented)
Click on the left panel to display the collapsed panel that has been implemented
Click the link in the fold panel to link to the new page. Although the tag target is the attribute value on this page
But it is also the new page. by default, Jquery is the first on the left.


Generally, not all click items or keep the Click status?
