It's best practice to avoid Check-boxes when possible. This is because they are very hard to report on (you can't group by them and get unique counts per option, for example). Additionally, the only workaround is to build one section per option in a report (and it still displays oddly). This will guide you to a workaround using linking fields that will allow multiple choices, grouping will be possible, and you will no longer need to build one section per report.
Real World Example
Let's say we want to track our client's favorite colors. They will have 5 options: blue, green, red, black, or yellow. We want them to be able to select multiple choices as well as be able to group on them in reporting as well as not have to build multiple sections per option chosen.
Our first item will be to create 2 Tier 2 forms under the Individual Tier 1.
Favorite Colors: we will begin by creating this Tier 2, it will only have a Date field, don't forget to publish the form.
2. Favorite Colors (Options): This will also be a Tier 2 form under the Individual Tier 1. It will have 1 field (dropdown) of "Pick a Color" with our 5 options. Don't forget to publish the form
Next, we will want to create a linking field onto our "Favorite Colors" form with the following settings:
Display Name: Pick Favorite Colors
Linked To: Favorite Colors (Options)
Link Relationship: Many to 1 (this will allow them to pick multiple colors but each color only once)
Same Folder Linking: Yes
Wizard Style Linking: Yes
Once this has been created you will need to publish the form one more time. Double check the linking field settings again, make sure they match the screenshot above. If they do not, re-adjust them one more time and publish the form one more time.
Next, we will need to go back to our other form of "Favorite Colors (Options)" to make a couple final adjustments to ensure a proper workflow.
Click the gear for the Form Properties
Enable "Hide from Document Folder"
Click the Section Properties for "Linked 'Favorite Colors' Records"
Finally, we will publish the form and now we have completed the setup portion of this article. Next, we will overview how to use this alternative setup.
Once we are in an Individual's Document Folder we will hover over Actions
Select "Create New"
First we will fill out the date
Next, we will select the New button
Pick the first color, Orange, in this example
Choose "Store Linked Record"
We can see that "Orange" was chosen for our first color. If this was a mistake you may click "Edit Record" to update the color choice or the X over to the far right to "un-check" that option
We will want to pick another color, click the New button, and do the same process we just did but pick Black this time
After it is saved we can see the colors which were chosen (you can even click there to update them if needed)
If you realized you chose one that you shouldn't have just un-check the check under the Active column for the proper color. Remember to Save Record if you do this.
Building A Report
Building the report will be slightly different than usual since this setup actually uses 2 different forms. Let's say we want to know the First Name, Last Name, Date, and all of the Favorite Colors chosen. We will have 3 forms in our report: Individual, Favorite Colors, and Favorite Colors (Options).
We need the First field from the Individual Form
The Last field from the Individual Form
The Date field from the Favorite Colors form
Do not bring in Description, Date Added, or Date Modified from the Pick Favorite Colors. Even though this is the linking field the data is stored in a different form. We don't need these to make a proper report.
Drag in the Pick a Color field from the Favorite Colors (Options) form
In the "Forms" area of the Section click on the form name "Favorite Colors (Options)"
In the Connected To area choose Favorite Colors. This is very important!
Apply (Note: you may need to refresh the browser for the report to update)
Now, once that is all complete we will "Group" by the "Pick a Color" column. Open the column properties and select "Yes" under "Group By This Column"
Finally, publish and run the report.
Notice that John Smith shows one time per color, just as we were expecting
This report can be modified and filtered further for your reporting needs
