Extending Columns Blueprint

I tried to extend columns with but couldnt achive.

According to document:

Fields, sections, tabs and entire blueprint layouts can be reused within your blueprints.

Did I misunderstand?

Here my blueprints:

site.yml

title: Site

columns:        
    left:
        width: 1/2
        sections:
            # sections
                
    right:
        width: 1/2
        sections:
            # sections

    extends: sections/site

sections/site.yml

customLeft:
    width: 1/2
    sections:
        # sections
            
customRight:
    width: 1/2
    sections:
        # sections

In above sample, extended elements do not appear and no any error.

You can extend a single column, but not columns in general, I think.

columns:
  customcol:
    extends: columns/costumcol

Or you can extend a complete layout, no matter if it contains tabs or columns.

Hmm, you right. I checked the about line and will not work :frowning:

I just wanted to customize some of the template (user defined dynamic theme)

Thank you so much, i’ll try complete layout that used it before.

You can even get pretty creative:
site/columns/customcols.yml

columns:
  maincol:
    width: 2/3
    sections:
      menusection:
        type: fields
        fields:
          menu:
            type: structure
            fields:
              level1entry:
                type: pages
              level2:
                type: structure
                fields:
                  level2entry:
                    type: pages
      comments:
        type: pages
        parent: kirby.page("comments")
        create: comment
        template: comment

  aside:
    width: 1/3
    sections:
      notes: sections/notes
      pages:
        type: pages
        create: default
        template:
          - about
          - home
          - default

Version 1 site.yml: Unset columns and sections within columns

title: Site
extends: columns/customcols
columns:
  maincol: false
  aside:
    sections:
      pages: false

Version 2 site.yml: Unset sections within columns

title: Site
extends: columns/customcols
columns:
  maincol:
    sections:
      menusection: false
  aside:
    sections:
      notes: false

Version 3 site.yml: Extend the aside column with a new section

title: Site
extends: columns/customcols
columns:
  aside:
    extends: aside
    sections:
      info:
        type: info
        text: Some text

Or extend the sections within and so on…

I’m a little ambitious :sweat_smile:

I solved this issue with adding just one line to Cms/Blueprint.php file.
Can we add such a feature? And may I ask your review?
It would be a nice feature to extends the columns as well :innocent:

Solution

Adding following line:

$columns = $this->extend($columns);

Before the foreach loop in 381. line:

I can PR if you want me to, but I’m not very good at unit tests.

I can’t review this and have to leave this to the devs.

Ok, should I add kirby ideas to review?

Yes, it’s an ideas issue. You can of course create a PR but they usually want unit tests.

Although I wonder what would be the advantage since we have all the options I mentioned above? You can even add additional columns:

title: Site
extends: columns/customcols
columns:
  newcol:
    width: 1/1
    sections:
      newsec:
        type: info
        text: Some other text

This will give you everything in customcols + the additional newcol column

So the only difference would be the position of the extends directive.

You right! But with this way only for CUSTOM + BASE.
With extending columns feature user design unlimited layouts.

  • CUSTOM + BASE
  • BASE + CUSTOM
  • CUSTOM + CUSTOM + BASE
  • CUSTOM + BASE + CUSTOM

For example i need in my prod website like that (User Defined Layout):

Untitled%20Diagram

True.

In the solution I found there is a bug like putting all the columns on top like your solution :grimacing: but devs will already review and test.

Best solution is Version 3 site.yml: Extend the aside column with a new section for now :innocent:

I gave you trouble again :pray:

In addition, we cannot extend/reuse multiple sections like that:

default.yml

column:
    left:
        width: 1/2
        extends: sections/custom

sections/custom.yml

sections:
    # section01
    # section02
    # section03
