Adding a tooltip to an input box

If you are using bootstrap (I am using version 4.0), feel free to try the following code.

<input data-toggle="tooltip" data-placement="top" title="This is the text of the tooltip" value="44"/>

data-placement can be top, right, bottom or left

It seems to be a bug, it work for all input type that aren't textbox (checkboxes, radio,...)

There is a quick workaround that will work.

<div data-tip="This is the text of the tooltip2">
    <input type="text" name="test" value="44"/>
</div>

I know this is a question regarding the CSS.Tooltips library. However, for anyone else came here resulting from google search "tooltip for input box" like I did, here is the simplest way:

<input title="This is the text of the tooltip" value="44"/>

<input type="name" placeholder="First Name" title="First Name" />

title="First Name" solves my proble. it worked with bootstrap.
