Block configuration

Whether a block appears on a page depends on a number of factors.

• First, the block must be enabled by checking its "enabled" box on the block management page;
• Second, the block's custom visibility settings must permit the block to be displayed for a given user. You can configure a block to appear always; to be displayed by default unless disabled by individual user preferences, or to be disabled by default but visible if enabled by individual users. Individual users can select or disable optional blocks from their "my account" page;
• Next, whether the block appears on pages for a given section of the site can be configured by the administrator by setting the block's path;
• The block can be configured to appear only for certain content types;
• Finally, if the throttle module has been enabled, and the block has its throttle box checked on the block management page, then it will only appear if the site's traffic is below a given threshold.

Once you have configured a block to appear as required on specific pages and in the correct column, you may wish to adjust the block's weight to position the block vertically within its column. A block's weight is set via a pull-down selector on the block management page. Heavier blocks (those with a more positive weight) "sink" to the bottom of a column, while lighter blocks "float" towards the top.

More information can be found in the modules section of the handbook on block.
