TWebEdit Hint shown twice with Bootstrap active

Entered a Hint on a TWebEdit, set ShowHint to true and when I hover the edit, this is the result I see in the browser:

So it's Bootstrap showing the Hint (aka tooltip) above the edit as well as it's shown the classic VCL style below the edit.

Here is the relevant HTML:

      <div class="row">
        <div class="col-md-6">
          <div class="form-group mb-3">
            <label for="EdUsername" class="form-label required">Benutzername</label>
            <input type="text" class="form-control" id="EdUsername" required>

How to decide for just the one or the other method, but not both?

Thank you!

I tested this with your HTML template and with Bootstrap 5.2.3 enabled and added the code

procedure TForm3.WebButton1Click(Sender: TObject);
  webedit1.Hint := 'test';
  webedit1.SHowHint := true;


but I could not see this behavior here. Setting the hint for the edit in code just adds the title attribute to the HTML INPUT element.

If I enter the Hint at design time, I get the behaviour I described above, which is both types of hints are displayed.

If I add the Hint at runtime, as you did, I get the Bootstrap style hint only (no VCL-style hint is shown and no title attribute is added). Tested with both, Bootstrap 5.2.3 as well as current 5.3.3. But I also load a couple more js libraries (jquery,popper,leaflet), which may make a difference.

If I only want the "VCL style" hint only, which I do, I need to add the Hint at design time and do the following (ChatGPT is my hero...):

  1. Add "data-bs-toggle="tooltip"" to the input element, like so
    <input type="text" class="form-control" id="EdUsername" required 
  1. Add script to execute during WebFormShow(), which disables all Bootstrap style tooltips (being tagged as above) but leaves VCL-style hints enabled:

Thanks for informing about the solution found.
