I'm developing a component for the front end (Joomla 3.x version).

I have used Bootstrap 3 for all the component views. I know Joomla is using bootstrap 2, so I unset the bootstrap 2 css & js files in my componentname.php and added the bootstrap 3 CSS and Javascript files.

The text box is not showing correctly (height of the text box is very low) and the form fields are 100% width.

How can I solve the text box problem and reduce the width of form controls ?

Thanks in advance.


$script = JURI::Root(true).'/media/jui/js/bootstrap.min.js';
unset ($script);

$css = JURI::Root(true).'/media/jui/css/bootstrap.min.css';
unset ($css);


<div class="form-group">
<label  for="parent_id" class=" hasTooltip required">Add Group</label>
    <select name="parent_id" class="inputbox" id="parent_id"  size="1">
    <option value="1">yes</option>
    <option value="0">No</option>

<div class="form-group">
    <label  for="firstname" class=" hasTooltip required" title="">Enter First name</label>
    <input class="form-control" type="text" name="firstname" id="firstname"   /> 
  <div class="form-group">
    <label  for="lastname" class=" hasTooltip required" title="">Enter First name</label>
    <input class="form-control" type="text" name="lastname" id="lastname"   /> 
 <div class="form-group">
    <label  for="sub_fmt" class=" hasTooltip required" title="">Enter Long Text</label>
    <textarea name='sub_fmt' id='sub_fmt' rows='3' class="form-control" cols='40'></textarea>

  • In my experience, unsetting bootstrap will create more headache than solution, especially when you're still willing to use the Joomla frontend content editing.

  • Can you please suggest a way to implement bootstrap 3 ? Because I need to use bootstrap 3 only.

  • Form fields have a width of 100% by default, see this: getbootstrap.com/css/#forms

There are advanced techniques implemented by template developers to support BS3. For example, loading first their own rendering classes to replace core rendering classes. Unsetting BS2 is not an option.

In my opinion, this can be implemented in a template, but it is overkill for a component (not in charge of the general style).

T3 framework is a nice example about how it can be done: http://www.t3-framework.org/downloads.html
