Initially, we have row_height=64 in my code and I want to add two buttons where one button changes the row_height to 36 and when I click the second button it will change to its original row_heigt which is 64.
how I can implement this?

Hello,
You can set the value to the gantt.config.row_height parameter, then you need to call the render method to repaint the changes:
https://docs.dhtmlx.com/gantt/api__gantt_render.html

Here is the snippet:

function changeRowHeight(value) {
gantt.config.row_height = value;
gantt.render();
}

    document.addEventListener("click", (event) => {
        const dataAction = event.target.getAttribute('data-action');
        if (dataAction) {
            switch (dataAction) {
                default: {
                    const images = document.querySelectorAll(".img-circle");
                    images.forEach(e => {
                        if (e.classList.contains('hidden')) {
                            e.classList.remove('hidden');
                        } else {
                            e.classList.add('hidden');
                        }
                    });
                    const profileImages = document.querySelectorAll(".profile-icon");
                    profileImages.forEach(e => {
                        if (e.classList.contains('hidden')) {
                            e.classList.remove('hidden');
                        } else {
                            e.classList.add('hidden');
                        }
                    });
                    const designation = document.querySelectorAll(".row-subheading");
                    designation.forEach(e => {
                        if (e.classList.contains('hidden')) {
                            e.classList.remove('hidden');
                        } else {
                            e.classList.add('hidden');
                        }
                    });
                    changeRowHeight(34);
                }
            }
        }
    });

i am using this code after adding that changerowHeight function my switch button is not working means its not checking after clicking on that so please help me on this.
I think gantt.render is making interrupt on making switch button work.
so do we have any other ways to make this work without including gantt.render.

Hello,
The render method only repaints the data in Gantt. It shouldn’t affect anything outside the Gantt container.
I tried to reproduce the issue in the snippet, but the row height is changed correctly:

It is hard to suggest what might be wrong as I don’t see your code.
Please add your configuration to the following snippet and make sure that the issue is reproduced there:

Then, click on the Save button and send me the link.
Or send me a ready demo with all the necessary JavaScript and CSS files so that I can reproduce the issue locally.

add changerowHeight button in the place of starttime in the sidecolumn then write this code then you see it is not working.
