When I set 2 data-targets to an toggle-button containing data-toggle="collapse", class collapsed cannot be added properly after the button is actived.

As title,

1. if I set one object (#sidebar) to data-target, class collapsed will be added after I click the button.

2. if I set two objects (#sidebar, #content) to data-target, class collapsed will **_NOT_** be added after I click the button. 3. why I set 2 data-targets. class 'in' will be toggled to #sidebar, #content, with which I toggle the sidebar and reset the margin-left of #content using css .XX.in{display:xx; margin-left:xx} 4. why I need class 'collapse' for toggle button I'd like to use css .collaspse.glyphicon-indent-right{content: '\XXX'} to toggle glyphicon-right or left 5. Could you help to provide any method that meets my need without any additional javascript?

Duplicate report of #17643 I think, at least for v4.

hi bro
I am using bootstrap v3 not v4. And both targets can be toggled. That's not the question I ask about.
I mean collapse in can be added and removed to the toggleE but collapseD can not be added to toggleR if I set 2 data-targets like #navbar #content. However the toggleR can be toggled with class collapseD if I set only one data-target. It is not the same issue with #17643. Did you misunderstand me?
