The tooltips appeal and activity has kept almost the exact same in both the Bootstrap 3 and 4 versions because these certainly perform work very efficiently-- completely nothing much more to get demanded from them.
One technique to boot up all of the tooltips on a page would be to select them by simply their
$(function () $('[data-toggle="tooltip"]').tooltip() )
4 approaches are easily available: top, right, bottom, and left coordinated.
Hover over the switches below to observe their tooltips.
<button type="button" class="btn btn-secondary" data-toggle="tooltip" data-placement="top" title="Tooltip on top"> Tooltip on top </button> <button type="button" class="btn btn-secondary" data-toggle="tooltip" data-placement="right" title="Tooltip on right"> Tooltip on right </button> <button type="button" class="btn btn-secondary" data-toggle="tooltip" data-placement="bottom" title="Tooltip on bottom"> Tooltip on bottom </button> <button type="button" class="btn btn-secondary" data-toggle="tooltip" data-placement="left" title="Tooltip on left"> Tooltip on left </button>

A factor to think about here is the amount of information that appears to be applied into the # attribute and ultimately-- the placement of the tooltip depending on the position of the major element on a display. The tooltips should be exactly this-- quick significant suggestions-- setting too much info might actually even confuse the site visitor rather than assist getting around.
Additionally if the major element is too near an edge of the viewport mading the tooltip alongside this very border might actually bring about the pop-up text to flow out of the viewport and the information within it to become practically unfunctional.
