Error encountered when attempting to trigger a Bootstrap dropdown within a designated div

When using React JS, I encountered an issue when trying to trigger a dropdown that was nested inside a div with the class name "row". Initially, I placed the data-toggle and data-target attributes inside the div, like so:

<div className="row">
  <div
    className="col-lg-6"
    id="dropdownMenuButton"
    data-toggle="dropdown"
    aria-haspopup="true"
    aria-expanded="false"
  >
      <div className="times">
        <span className="dot" />
        <span className="dot" />
        <span className="dot" />
      </div>
  </div>
</div>

Unfortunately, this configuration resulted in the following error message:

TypeError: Cannot read property 'setAttribute' of null

After some troubleshooting, I found that moving the data-toggle attribute outside of the "row" class resolved the issue. However, this solution was not ideal as it caused the trigger length to be equal to the width of the entire "row".

Answer №1

Include a col-2 division within the row and position the toggle button there. Utilize fontawesome icons to craft a triple-bar icon for the button.

<div class="row">
    <div class="col-2">
        <div class="dropdown">
          <button class="btn btn-secondary" type="button" id="dropdownMenuButton" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
            <i class="fas fa-bars"></i>
          </button>
          <div class="dropdown-menu" aria-labelledby="dropdownMenuButton">
            <a class="dropdown-item" href="#">Action</a>
            <a class="dropdown-item" href="#">Another action</a>
            <a class="dropdown-item" href="#">Something else here</a>
          </div>
        </div>
    </div>
</div>
