Limit LayerList dragEnabled to top level

Hello,

I have a layer list with dragEnabled set to true. This is a nice feature but one of my apps I would like to lock this down so that users can't drag children of a group layer outside of the group layer. Is this possible? If not could, I would like to request this feature be added.

Hi @CalebSchwind ,

You can set the childrenSortable property on the ListItem within the listItemCreatedFunction . You could limit this to just group layers or set it for all child layers like this.

https://codepen.io/sagewall/pen/mybqbXm

// A function that executes each time a ListItem is created for a layer. arcgisLayerList.listItemCreatedFunction = (event) => { // The event object contains an item property. // It is a ListItem referencing the associated layer // and other properties. You can control the visibility of the // item, its title, and actions using this object. const { item } = event; // Prevent drag and drop on all child layers item.childrenSortable = false; // Or if you wanted to limit to group layers // if (item.layer.type === "group") { // item.childrenSortable = false; // } }
