Although a check box can have three states as explained in this blog , see screenshot below, I focus in this blog on true and false.

in this blog I focus on two options instead of three


Below a simple table I use to show the power of True(). We start with the If statement using a checkbox:

Checkbox inside an If-statement

The only thing we wrote was the name of the column: ‘CheckBox’ and this works.

No need to write :

Nor to write:

Nor this option:

The filter

The same inside a filter, see below:

Here likewise, all the other options would work as well, but the simple check box does the job.

The mains lesson is that a checkbox is True() by default and this insight you can apply elsewhere as well, like in setting up automation rules. Below a last example related to check boxes living on the canvas:

Below two buttons that together result in 4 options.

The options on the canvas I wrote :

When a check box is checked, you simply note the default state (true) and if not, you add .Not() . It is as easy as this and fast in writing. This logic permits for setting up a schema really fast.

While templating I make use of this logic to keep track of options users make in the doc. The named formulas help me to see what I am doing.
