how to use place holder in textarea input form attributes.

T-onetech

I find it difficult to use the placeholder attribute, I want to achieve something like this:
{
"label": "Weekly Evangelism:",
"name": "weekly_evangelism",
"type": "textarea",
"placeholder": "No of slips Followed"
},

{
    label:  "Weekly Evangelism:",
    name:  "weekly_evangelism",
    type:    "textarea",
    attr: {
       placeholder: "No of slips Followed"
     }
},

with "select" fields it is slightly different. You don't use "attr" there but you can specify the placeholder just like any other field attribute:
https://editor.datatables.net/reference/field/select

like this for example:

}, {
    label: "yourLabel",
    name:  "yourField",
    type: "select",
    multiple: true,
    placeholderDisabled: false,
    placeholder: "your placeholder"
}, {
