| WARNING
| -------
| You might have to edit the file {dist}/base.html
| by adding nav in the following way:
| This line:\t<ul class="navbar-nav mr-auto">
| Becomes:\t<ul class="nav navbar-nav mr-auto">
|
| This will prevent the navigation bar from expanding
| such that some elements can not be seen.
| Refer to this pull request:

| If the above pull request is merged and flask-admin
| is on a new release after the merge,
| then this step is not needed.
