This list is constantly growing and each module's support has usually been implemented because of either extremely high usage or the fact it was designed explicitly for use with this base theme and has maintainers in both projects. **Supported modules:** - [Admin Menu](https://www.drupal.org/project/admin_menu) - [Bootstrap Core](https://www.drupal.org/project/bootstrap_core) - [Disable Messages](https://www.drupal.org/project/disable_messages) - [jQuery Update](https://www.drupal.org/project/jquery_update) - [Icon API](https://www.drupal.org/project/icon) - [Path Breadcrumbs](https://www.drupal.org/project/path_breadcrumbs) - [Picture](https://www.drupal.org/project/picture) - [Views](https://www.drupal.org/project/picture) _(partial support)_ - [Webform](https://www.drupal.org/project/webform) _(partial support)_ The following modules are "un-supported modules" and are not documented by the [Drupal Bootstrap] base theme. This does not mean that the base theme will not work with them or that they are "bad". It simply means that this project does not have the time, energy or effort it would take to document "every possible scenario". It is certainly possible that some of these modules may eventually become "officially" supported. That will happen only, of course, if there are enough people to help contribute solid solutions and make supporting them by the base theme maintainers a relatively "easy" task. Some of these modules may have blogs or videos floating around on the internet. However, if you choose to use one of these modules, you are really doing so at your own expense. Do not expect support from this base theme or the project you are attempting to integrate the base theme with. **"Un-supported" modules:** - Color module (in core) - [Bootstrap API](https://www.drupal.org/project/bootstrap_api) - [Bootstrap Library](https://www.drupal.org/project/bootstrap_library) - [Display Suite](https://www.drupal.org/project/ds) - [Display Suite Bootstrap Layouts](https://www.drupal.org/project/ds_bootstrap_layouts) - [LESS module](https://www.drupal.org/project/less) - [Panels](https://www.drupal.org/project/panels) - [Panels Bootstrap Layouts](https://www.drupal.org/project/panels_bootstrap_layouts) --- ### Q: Do you support Internet Explorer? {#ie} **A: No, not "officially"** The [Bootstrap Framework] itself does not officially support older Internet Explorer [compatibility modes](https://getbootstrap.com/docs/3.3/getting-started/#support-ie-compatibility-modes). To ensure you are using the latest rendering mode for IE, consider installing the [HTML5 Tools](https://www.drupal.org/project/html5_tools) module. Internet Explorer 8 requires the use of [Respond.js] to enable media queries (Responsive Web Design). However, [Respond.js] does not work with CSS that is referenced via a CSS `@import` statement, which is the default way Drupal adds CSS files to a page when CSS aggregation is disabled. To ensure [Respond.js] works properly, enable CSS aggregation at the bottom of: `admin/config/development/performance`. --- ### Q: Is Drupal Bootstrap a module or theme? {#module-or-theme} **A: Theme** More specifically a base theme. It is _not_ a module. Modules are allowed to participate in certain hooks, while themes cannot. This is a very important concept to understand and limits themes from participating in a wider range of functionality. --- ### Q: What does the JavaScript error `TypeError: $(...).on is not a function` mean? {#jquery} Drupal 7 ships with the `1.4.4` version of jQuery out-of-the-box. The [$.on()](http://api.jquery.com/on/) method was introduced several versions after this in jQuery version `1.7`. You must upgrade your site or sub-theme's jQuery Version by installing (and properly configuring) the [jQuery Update] module to use a jQuery version compatible with the [Bootstrap Framework]. This is typically a version greater than or equal to `1.9`. Ensuring jQuery compatibilities between Drupal, the [Bootstrap Framework] and other plugins/modules does not fall within the scope of this base theme's documentation or support. --- ### Q: Where can I discuss an issue in real time? {#irc} **A: In IRC** The [Drupal Bootstrap] project and its maintainers use the `#drupal-bootstrap` channel on the freenode.net IRC network to communicate in real time. Please read the following for more information on how to the community uses this technology: [Chat with the Drupal Community on IRC](https://www.drupal.org/irc). Please keep in mind though, this **IS NOT** a "support" channel. It's primary use is to discuss issues and to help fix bugs with the base theme itself. --- ### Q: Where should I make changes? {#changes} **A: In a custom sub-theme** You should **never** modify any theme or sub-theme that is packaged and released from Drupal.org. If you do, all changes you have made would be lost once that theme is updated. This makes keeping track of changes next to impossible. Instead, you should create a custom sub-theme that isn't hosted on Drupal.org.

This action stores the settings in the {variables} table of the database. The workflow for theme_get_setting() merges the settings from the database on top of the settings found in the theme's `.info` file. You need to remove the variable `theme_[theme_name]_settings` from the database, where `[theme_name]` is your sub-theme's machine name (e.g. if your sub-theme machine name is `my_bootstrap_subtheme`, the variable name would be `theme_my_bootstrap_subtheme_settings`). The easiest way to do accomplish this task is to use the following [Drush] command: `theme_my_bootstrap_subtheme_settings` If you do not have or use [Drush], you will either have to manually delete this variable from the database or create an [update hook](https://api.drupal.org/api/drupal/modules%21system%21system.api.php/function/hook_update_N/7) in a custom module that deletes the variable for you: ```php /** * Remove the 'theme_my_bootstrap_subtheme_settings' variable. */ function hook_update_N() { variable_del('theme_my_bootstrap_subtheme_settings'); } ``` [Drush]: http://www.drush.org [Drupal Bootstrap]: https://www.drupal.org/project/bootstrap [Bootstrap Framework]: https://getbootstrap.com/docs/3.3/ [jQuery Update]: https://www.drupal.org/project/jquery_update
