Hi Tomasz,
Thanks for contacting Syncfusion.
We can enable or disable the automatic update of timeline on editing action by using the property updateTimescaleView in timelineSettings property. When it is disabled, timeline will not update on editing action. Please find the below code example.
<template>
<ejs-gantt ref='gantt' id="GanttContainer"
:timelineSettings="timelineSettings"
//...>
</ejs-gantt>
</template>
<script>
//...
export default {
data: function() {
return{
//...
timelineSettings: {
updateTimescaleView: false
},
};
},
</script> |
Please find the sample from below link.
Please get back to us if you require further assistance on this.
Regards,
Gurunathan
