Kendo grid with default Columns - kendo-grid

Question

I want to show to users subset of columns and allow them to add extra columns if needed. I am struggling to load only subset of columns on load. Please find the code below I have done.
<kendo-grid k-options="vm.mainGridOptions"
k-columns="vm.mainGridColumns"
k-sortable="true"
k-filterable="{mode: 'row'}"
k-column-menu="true"
k-serverFiltering="false"
k-pageSize="10"
k-pageable="{ pageSizes: [5, 10, 25, 50, 100] }"> </kendo-grid>
Controller code
var mainGridDataSource = new kendo.data.DataSource({
transport: { read: mainGridReadEventHandler, cache: true },
serverFiltering: false,
page: 1,
pageSize: 10,
schema: {
data: 'data',
total: 'total',
model: {
fields: {
customerName: { type: "string" },
serviceAccountStatus: { type: "string" },
customerNumber: { type: "string" },
serviceType: { type: "string" },
utilityAccountNumber: { type: "string" },
serviceAddress: { type: "string" },
billingAccountNumber: { type: "string" },
utility: { type: "string" },
phoneNumber: { type: "string" },
email: { type: "string" }
}
}
}
});
vm.mainGridColumns = [
{
field: "customerName",
title: "Name",
template:
"<a ui-sref='resiservice.account-search.customer-details({ customerId:${customerId}, serviceAccountId:${serviceAccountId} })'>${customerName}</a>"
},
{
field: "serviceAccountStatus",
title: "Status"
},
{
field: "customerNumber",
title: "NAP Customer #"
},
{
field: "serviceType",
title: "Commodity"
},
{
field: "utilityAccountNumber",
title: "Utility/Account #"
},
{
field: "serviceAddress",
title: "Service Address"
},
{
field: "billingAccountNumber",
title: "NAP Account #"
},
{
field: "utility",
title: "Utility"
},
{
field: "phoneNumber",
title: "Phone #"
},
{
field: "email",
title: "Email Address"
}
];
Currently columns list coming like this first time
And i want to achive like this

Answer 1

Use columns.hidden property to hide a column, i.e.
{
field: "utility",
title: "Utility",
hidden: true
},
{
field: "phoneNumber",
title: "Phone #",
hidden: true
},
{
field: "email",
title: "Email Address",
hidden: true
}
For example:

The column is still visible on the list of columns in menu.
