Angular Bootstrap tooltip

Tooltips are a convenient way of presenting additional information to your user. They are tiny little clouds with a brief text message, triggered by clicking on specified element or hovering over it.

They significantly increase User Experience, especially with advanced UI elements, which often require additional explanation.


Examples

Four options are available: top, right, bottom, and left aligned.

Add placement="top/left/bottom/right" to the <button> tag.



<button type="button" class="btn btn-primary waves-light" mdbTooltip="Tooltip on top" placement="top" mdbRippleRadius>
  Tooltip on top
</button>

<button type="button" class="btn btn-primary waves-light" mdbTooltip="Tooltip on right" placement="right" mdbRippleRadius>
  Tooltip on right
</button>

<button type="button" class="btn btn-primary waves-light" mdbTooltip="Tooltip on bottom" placement="bottom" mdbRippleRadius>
