Remove extra column of icons from Angular UI-Grid TreeView

Question

I want to remove extra column of icons for expand and collapse and merge it with my main treebase column. Plunkr Source

In the following link you can see that on a tree

Answer 1

The rowHeader can be hidden just by a property,

showTreeRowHeader: false,

To have the tree expand buttons as part of the first column, you just need to replicate the template as part of the cell. Define the cell template like this,

 { name: 'name', width: '30%' , cellTemplate : "<div class=\"ui-grid-cell-contents\" title=\"TOOLTIP\"><div style=\"float:left;\" class=\"ui-grid-tree-base-row-header-buttons\" ng-class=\"{'ui-grid-tree-base-header': row.treeLevel > -1 }\" ng-click=\"grid.appScope.toggleRow(row,evt)\"><i ng-class=\"{'ui-grid-icon-minus-squared': ( ( grid.options.showTreeExpandNoChildren && row.treeLevel > -1 ) || ( row.treeNode.children && row.treeNode.children.length > 0 ) ) && row.treeNode.state === 'expanded', 'ui-grid-icon-plus-squared': ( ( grid.options.showTreeExpandNoChildren && row.treeLevel > -1 ) || ( row.treeNode.children && row.treeNode.children.length > 0 ) ) && row.treeNode.state === 'collapsed'}\" ng-style=\"{'padding-left': grid.options.treeIndent * row.treeLevel + 'px'}\"></i> &nbsp;</div>{{COL_FIELD CUSTOM_FILTERS}}</div>" },

This plnkr shows a working model, http://plnkr.co/edit/rkHZs0?p=preview

Now to change the icons, all you need to do is to change the

<i ng-class=\"{'ui-grid-icon-minus-squared': ( ( grid.options.showTreeExpandNoChildren && row.treeLevel > -1 ) || ( row.treeNode.children && row.treeNode.children.length > 0 ) ) && row.treeNode.state === 'expanded', 'ui-grid-icon-plus-squared': ( ( grid.options.showTreeExpandNoChildren && row.treeLevel > -1 ) || ( row.treeNode.children && row.treeNode.children.length > 0 ) ) && row.treeNode.state === 'collapsed'}\" ng-style=\"{'padding-left': grid.options.treeIndent * row.treeLevel + 'px'}\"></i>

in the cell template. The default template uses ui-grid-icon-plus-squared and ui-grid-icon-minus-squared and can be changed to whatever you like.

The Previous answer of adding following cell template in the column defenition worked for me,

cellTemplate: "<div class=\"ui-grid-cell-contents\" title=\"TOOLTIP\"><div style=\"float:left;\" class=\"ui-grid-tree-base-row-header-buttons\" ng-class=\"{'ui-grid-tree-base-header': row.treeLevel > -1 }\" ng-click=\"grid.appScope.toggleRow(row,evt)\"><i ng-class=\"{'ui-grid-icon-minus-squared': ( ( grid.options.showTreeExpandNoChildren && row.treeLevel > -1 ) || ( row.treeNode.children && row.treeNode.children.length > 0 ) ) && row.treeNode.state === 'expanded', 'ui-grid-icon-plus-squared': ( ( grid.options.showTreeExpandNoChildren && row.treeLevel > -1 ) || ( row.treeNode.children && row.treeNode.children.length > 0 ) ) && row.treeNode.state === 'collapsed'}\" ng-style=\"{'padding-left': grid.options.treeIndent * row.treeLevel + 'px'}\"></i> &nbsp;</div>{{COL_FIELD CUSTOM_FILTERS}}</div>"

But remember adding uiGridTreeBaseService to the app controller and then add following method to your controller,

$scope.toggleRow = function(row, evt) {
    uiGridTreeBaseService.toggleRowTreeState($scope.gridApi.grid, row, evt);
};

If you miss the last two steps then tree won't expand on click of plus sign.

After this, I faced some difficulty with the rows which don't have any children. Their indentation was not proper. So following is the cell template I finally used,

 cellTemplate: "<div class=\"ui-grid-cell-contents\" title=\"TOOLTIP\"><div style=\"float:left;\" class=\"ui-grid-tree-base-row-header-buttons\" ng-class=\"{'ui-grid-tree-base-header': row.treeLevel > -1 }\" ng-click=\"grid.appScope.toggleRow(row,evt)\"><i ng-class=\"{'ui-grid-icon-down-dir': ( ( grid.options.showTreeExpandNoChildren && row.treeLevel > -1 ) || ( row.treeNode.children && row.treeNode.children.length > 0 ) ) && row.treeNode.state === 'expanded', 'ui-grid-icon-right-dir': ( ( grid.options.showTreeExpandNoChildren && row.treeLevel > -1 ) || ( row.treeNode.children && row.treeNode.children.length > 0 ) ) && row.treeNode.state === 'collapsed', 'ui-grid-icon-blank': ( ( !grid.options.showTreeExpandNoChildren && row.treeLevel > -1 ) && !( row.treeNode.children && row.treeNode.children.length > 0 ) )}\" ng-style=\"{'padding-left': grid.options.treeIndent * row.treeLevel + 'px'}\"></i> &nbsp;</div>{{COL_FIELD CUSTOM_FILTERS}}</div>"

This keeps all the elememnts of same level with the same indent. Don't forget to set showTreeExpandNoChildren: false (if you are loading table data at one shot).
