Hide Columns in Your Online Class Listing Tables

Online Class Listing Tables are highly customizable, allowing you to showcase your class offerings by grouping classes, adding specific class information, hiding columns of information, and more!

It all starts with the basic Online Class Listing Table. There are 12 columns included in the basic table: Register, Class, Description, Days, Times, Gender, Ages, Openings, Class Starts, Class Ends, Session, and Tuition. 

This column order is set (hardcoded), and columns cannot be moved to a different order; however, it is possible to hide any of the columns in a table. For example, hide the Openings column or the Session column.

To hide columns from Online Class Listing Tables, a parameter is added to the basic JavaScript code and URL (link). Well, that certainly sounds very techie 🤓, doesn't it?  It sounds worse than it is, we promise! 

Let's step through it here and look at a couple of examples with the code and links. If you prefer a quicker study, check out the Speed Learning section in A Cheat Sheet for Customizing Your Online Class Listing Tables.

Parameter for Hiding Columns

To hide columns of information in an Online Class Listing Table, a parameter is added to the end of the basic Online Class Listing Table code after an ampersand symbol '&'. A parameter includes a variable and a value separated by the equals sign (=), e.g., hidecols=Openings or hidecols=Session.

The variable used to hide columns is hidecols. It is used only once in the parameter and can be used with multiple values separated by a comma.

The values that are paired with the hidecols variable are the column headers in the table, with the exception of the Class Starts column and the Class Ends column, which have slightly different parameter values.

Frequently Asked Questions

Q.  How can I control the width of each column in the table?

A.  The overall table width is automatic - it will shrink or stretch to fit into your content area or div.  The column width in each table is determined by the maximum character count in that column. The individual column widths can not be controlled by the HTML codes provided by Jackrabbit.  The only way to control them would be to have a website administrator use the table data and manipulate the output layout.  

If you are placing several tables on the same webpage, consider inserting a few rows of descriptive text between each table to visually break up the page.
