CHECKBOX (Free Format Question Type)
Warning:
Because of the complexities of the Free Format Question type, you must completely test your survey to ensure that it functions properly and that the data for your entire survey are being saved correctly.
General Information about Free Format Questions
The CHECKBOX variable is used for presenting a set of check boxes in your survey. Within the Free Format Variable dialog, specify a Free Format Variable with CHECKBOX as the Variable Type. Even though the response to each check box is stored independently as a unique variable name, you do not specify at this point each variable name associated with each check box. Specify the Number of Response Options, or the number of check boxes you have in the set. You may also specify the Min Checks and the Max Checks to force the respondent to check a certain number of check boxes (within the range you specified).
Within the HTML editing area, specify an <input> HTML tag with the type set to "checkbox" for each check box in the set. The easiest way to do this is by using the Free Format Tools button. When using the Free Format Tools button, Lighthouse Studio automatically provides default HTML with appropriate variable naming conventions.
Checkbox Select in Free Format
By default, Lighthouse questionnaires use graphical radio buttons/checkboxes (specified under Survey Settings, General Settings tab). The HTML used by Lighthouse Studio to display checkboxes is more complex than the standard HTML used to display checkboxes. You can use View Source within your browser to examine (and copy) the syntax Lighthouse Studio uses when displaying standard Select-type questions with checkboxes. But, a simpler solution is to use the Free Format Tools button that you access when editing the HTML section of Free Format questions using the pencil icon. It inserts template HTML, including the use of the Lighthouse Studio function called CheckSelect.
When you click Tools to add checkboxes, a dialog appears that lets you specify vertical, horizontal, or no table. The table provides a structure for displaying the checkboxes. Depending on the layout of your checkbox question, you'll select one of these options. We recommend you add the template structure and click the Preview button to see which layout best fits what you want to accomplish.
The name attribute for each <input> tag must be the name of the variable (all radio <input> tags should have the same name attribute). The VALUE attribute for each <input> tag should be set to a unique value, so you can determine which option the respondent selected (we recommend sequential integers starting with one).
