这个问题背后的原因是,bootstrap-tagsinput 类正在使用display: inline-block;
解决方案是,只需display: inline-block;
将display: block;
变更前
.bootstrap-tagsinput {
display: inline-block;
background-color: #fff;
border: 1px solid #ccc;
box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075);
padding: 4px 6px;
margin-bottom: 10px;
color: #555;
vertical-align: middle;
border-radius: 4px;
max-width: 100%;
line-height: 22px;
cursor: text;
}
改变后
.bootstrap-tagsinput {
display: block;
background-color: #fff;
border: 1px solid #ccc;
box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075);
padding: 4px 6px;
margin-bottom: 10px;
color: #555;
vertical-align: middle;
border-radius: 4px;
max-width: 100%;
line-height: 22px;
