The "True/False Field" gives you the ability to create a field which can either be true or false as its name suggests.
As you can see from the screenshot below, while setting up the field you can select the default value and what can be displayed in the frontend when you have toggled this field for either TRUE or FALSE.
Let's see what each option does.
|Name||The name will be used to identify the field. Leave this blank and Joomla will fill in a default value from the title.|
|Label||The label of the field to display.|
|Description||A description of the field that will be displayed in the label tooltip.|
|Required||Is this a mandatory field?|
|Default Choice||Choose the default choice to be between true or false or leave it blank|
|True Text||The text to be displayed in the frontend for the TRUE value|
|False Text||The text to be displayed in the frontend for the FALSE value|
Its usage is fairly simple. Once you set it up then while in the article edit screen you can select whether its value should be TRUE or FALSE
Take a look at the screenshot below to see how it could be displayed in your frontend.
