Resize column in 7.1.12 is not working

I have specified the resize value in both columns and layout.
gantt.config.columns = [
{ name: “$wbs”, label: “#”, tree: true, resize: true },
{
name: “text”,
label: “Title”,
align: “center”,
width: 60,
resize: true,
},]
gantt.config.layout = {
css: “gantt_container”,
rows: [
{
cols: [
{ view: “grid”, group: “grids”, scrollY: “scrollVer” },
{ resizer: true, width: 1 },
{
view: “timeline”,
scrollX: “scrollHor”,
scrollY: “scrollVer”,
},
{ view: “scrollbar”, id: “scrollVer”, group: “vertical” },
],
gravity: 2,
},
{ resizer: true, width: 1 },
{
config: resourceConfig,
cols: [
{
view: “resourceGrid”,
group: “grids”,
width: 435,
scrollY: “resourceVScroll”,
},
{ resizer: true, width: 1 },
{
view: “resourceTimeline”,
scrollX: “scrollHor”,
scrollY: “resourceVScroll”,
},
{ view: “scrollbar”, id: “resourceVScroll”, group: “vertical” },
],
gravity: 1,
},
{ view: “scrollbar”, id: “scrollHor” },
],
};

Hello Nivedha,
Most likely, you didn’t install the Pro/Trial version as the GPL version (that is installed by default) doesn’t have the feature to resize the grid and its columns:
https://docs.dhtmlx.com/gantt/desktop__specifying_columns.html#resizing
Gantt Layout Gantt Docs.

Here is the simple Angular demo where the resizers work out of the box:
https://files.dhtmlx.com/30d/b504d1ac61ed7565bad6afcf8b3721e2/angular13+gantt_7.1.12_Trial.zip

You can install the Pro/Trial version the following way:

  1. Unpack Gantt to a specific folder, for example, to /opt/gantt_pro
  2. Use the following command to install Gantt:
npm install /opt/gantt_pro

You can read more about installation methods in the following article:
