Conditional options/blocks

[cloetensbrecht]

Is there any way to create conditional options within a SelectField or conditional blocks within a BlockField?
I would like to manipulate the options/blocks depending on other doc field values:

Desired select example:

import {SelectField} from 'payload/types'

const optionsList1 = [
  {
    label: 'Option 1',
    value: 'option1'
  },
  {
    label: 'Option 2',
    value: 'opton2'
  }
]

const optionsList2 = [
  {
    label: 'Option 3',
    value: 'option3'
  },
  {
    label: 'Option 4',
    value: 'opton4'
  }
]

const selectField: SelectField = {
  name: 'select',
  label: 'Select',
  type: 'select',
  hasMany: false,
  options: ({anotherField}) => {
    if (anotherField === 'showOptionsList1') return optionsList1
    return optionsList2
  }
}

export default selectField

Desired blocks example:

import {Block, BlockField} from 'payload/types'
import {VideoBlock} from '../blocks/Video'
import {ImageBlock} from '../blocks/Image'
import {SpecialHomePageBlock} from '../blocks/SpecialHomePage'

const defaultPageBlocks: Block[] = [
  VideoBlock,
  ImageBlock,
]

const homePageBlocks: Block[] = [
 ...defaultPageBlocks,
  SpecialHomePageBlock
]

const blockField: BlockField = {
  label: 'Content',
  name: 'blocks',
  type: 'blocks',
  blocks: ({pageType}) => {
   if (pageType === 'home') return homePageBlocks
   return defaultPageBlocks
  }
}

export default blockField

I know that you can add conditions through the admin config, but this can only hide/show the field. So I could add different blockFields with other admin conditions, but in this case I can not use the same name again because a field name can only exist once.

Is there any solution to reach this?
