Cannot load children nodes when vertical chart is used
isnanmulia opened this issue · comments
I'm trying to create a structure such that initially it has depth of 2, vertical depth of 2, and every leaf nodes will load its children nodes from database when I click "+" icon.
I have tried using the horizontal version, and the children nodes of leaf nodes are successfully loaded from database when I click "fa-chevron-down" icon.
But when I change the structure into vertical (see first image), the chart isn't do the same thing. Instead, it throws error Uncaught TypeError: Cannot read property 'querySelectorAll' of null
.
Any workaround for this issue? Thanks before.
