twitter/bootstrap — Issue #2274: bootstrap collapse does not work with dynamic content
Author: waynebrantley

State: open

When you first click the link to open the collapsed area, the content is loaded - but the height is determined to be 0, if the request takes any time. Clicking the link to close and open again causes the loaded content to be shown - because the content was already there and the height is correct.
