I want to add custom element like that . Like combining of two task boxes. It doesnt need to have task properties. But selectable or editable must.
But I couldn’t find any example for it. In examples applying append svg to parent. But I need to add selectable and editable boxes like task box. If you help me I ’ will be happy. You can give a link for that. Thank you.
But
I have a form near the diagram. I 'm changing form according to element selected. So For this element I want to set my business settings separately for that. I need to call element selected event separately.
