Creating a Checklist from A item in another Checklist
Asked by Matt Juric:

I'm using a card-button to automatically create a "Top level" checklist. I know I can create all the other checklists individually but is there a way to create the "Sub level" checklists from the "Top level"? Something like

"For each check list item in checklist X, create checklist, add item to checklist...."?

So for instance if I create a checklist like this

Checklist A

Item 1

Item 2

Item 3

Can I then automatically look at this check list and create something like this.

Checklist Item 1

Do Stuff Item 1A

Do Stuff Item 1B

Do Stuff Item 1C

Checklist Item 2

Do Stuff Item 2A

Do Stuff Item 2B

Do Stuff Item 2C

Checklist Item 3

Do Stuff Item 3A

Do Stuff Item 3B

Do Stuff Item 3C

Thank You.

body: Hi, [@Matt Juric](/t5/user/viewprofilepage/user-id/5481730) Trello doesn't offer the ability to add a checklist item underneath another checklist item, however, you can create a sort of parent-child hierarchy with 3 levels using linked checklist items. This is useful if you need to add more information to the checklist items like descriptions, comments, or another layer of checklists.  

This is what it looks like if you're not familiar:

Using butler, you can set this up so any item you add to your "Tasks" checklist will automatically generate a new linked card. From there, you can add another checklist within your "task" cards.  

This will generate more cards on your board, but if you're on Premium, you can collapse the list to keep things a bit tidier or use the collapsed lists chrome extension if you're using Trello free/standard.  

If this looks like a viable solution for you, I'd be happy to share more info around how to set it up!

body: Oops, sorry I misread your post. If everything's templated, then you should be able to automate it with butler. Do you want it to be triggered when you create a checklist item?

For example, something like:

"When an item is added to a checklist, add the {checklistitemname} checklist from card "Templates" to the card."

So the idea would be to create a template card and pre-populate it with all the checklists and items.

body: What I have is I want to set up check list for our machine assembly. Our systems are set up with 1000 levels. So the main assembly is -0000, base is -1000 and so on.

I want to use a "Card-Button" that will create this layout. I would like to have something like.

"When I click the card button add checklist "Main assembly".

"Add Checklist item to "Main Assembly" "-1000"

"Add Checklist item to "Main Assembly" "-3000"

"Add Checklist item to "Main assembly" etc etc etc.

"Create new Checklist {Name of first item in Main Assembly Checklist}"

"Add Checklist Item to {Name of First item in Main Assembly Checklist} "Assembly released"

"Add Checklist Item to {Name of First item in Main Assembly Checklist} "All parts available for assembly"

"Add Checklist Item to {Name of First item in Main Assembly Checklist} "Assembly complete"

"Create new Checklist {Name of Second item in Main Assembly Checklist}"

"Add Checklist Item to {Name of Second item in Main Assembly Checklist} "Assembly released"

"Add Checklist Item to {Name of Second item in Main Assembly Checklist} "All parts available for assembly"

"Add Checklist Item to {Name of Second item in Main Assembly Checklist} "Assembly complete"

Rinse and repeat for all items on the checklist "Main assembly"

Again I know I can do all this by creating each checklist manually in the same manner that the I did above with the "Main assembly" checklist, but I'm looking at 15-20 checklist and if I can do it "Automagically" that would be way easier.

Thank You for your time,

Edit to add - As I looked at that my intention was "Can this be done in some sort of loop". Obviously if I had to do each step for each checklist it would be the same as if I just added the information for each checklist.

body: Will the checklist and checklist items be the same each time? Similar to what's mentioned above, you could add all the checklists to a template card and have the button pull from that template card. E.g.  

```
add the "Main Assembly" checklist from card "Template" to the card, add the "Tasks" checklist from card "Template" renamed to "-1000" to the card, and add the "Tasks" checklist from card "Tasks" renamed to "-3000" to the card
```

If you already have all the items listed down somewhere (like in a spreadsheet or doc), you can paste them into your template card to speed things up.

Thank You for your time.
