Dynamic shape, I need render list of elements

[VictorPulzz]

Introduction

Hello guys!
I'm workin with jointjs plus on BPMN, and I need render shape in Paper with dynamic content. (like react conditional rendering)
For example:

I have action, with dynamic content (highlighted in red)
May not have the first block
And the block with the user is replaced by the text “Not assigned”
My code example:

class Activity extends dia.Element {
    override preinitialize() {
      this.markup = util.svg/* xml */ `
        <rect @selector="body" />
        <text @selector="title" />
        <image @selector="avatar" />
      `;
    }

    override defaults() {
      return {
        ...super.defaults,
        type: STENCIL_SHAPES.ACTIVITY,
        size: STENCIL_SIZES[STENCIL_SHAPES.ACTIVITY],
        attrs: {
          body: {
            fill: ORIGINAL_SHAPE_BG,
            width: 'calc(w)',
            height: 'calc(h)',
            stroke: ORIGINAL_SHAPE_STROKE,
            strokeWidth: 1,
            rx: SHAPE_ROUNDED,
            ry: SHAPE_ROUNDED,
          },
          title: {
            x: 18,
            y: 15,
            fontFamily: 'Lato',
            fontSize: 12,
            fill: ORIGINAL_SHAPE_TEXT_COLOR,
            text: 'lorem asdad asdad asdad asdad asdad asdad asdad asdad asdad asdad asdad asdad asdad asdad asdad asdad asdad asdad asdad asdad asdad asdad asdad asdad',
            textWrap: {
              width: 'calc(w-50)',
              maxLineCount: 1,
              ellipsis: true,
            },
            textVerticalAnchor: 'top',
          },
        },
      };
    }
  }

Idea to think about, why not make makup dynamic in general (as a callback where custom properties would be sent to the parameter of this function) and the result of rendering could be changed depending on props.🤔

I resolved, creating custom View, and using renderMarkup, not clearable solution, but it works
