• I'm submitting a ...

  • feature request

• What is the current behavior?
  Currently, it's really hard to have nodes with different "state" or have something different than a text, like a button for example

• What is the expected behavior?
  Possibility to put whatever we want in a node, only having the node data parameters

• What is the motivation / use case for changing the behavior?
  This can be useful in many cases, like putting the type of the current node next to the text in a specific color or having a button instead of text to add a child to the node....

• Other information
  I forked the project and implements the solution following the liquor-tree implementation (a good vue2 tree library)
