特定のカタログアイテムをポータルから起票する際にzipファイルの添付を禁止したいのですが、何か良い方法はありますか？

テキストファイルをメインに添付したいと考えております。

you can use OOTB attachment variable in your catalog item and then add list of allowed extensions via variable attributes

Attachment Variable 

allowed_extensions=jpg,png,pdf,doc,docx 

OR

if you are planning to use the OOTB paper-clip icon and want to restrict then you will require custom onSubmit script for this

sample like this, it grabs all the file names and then you can check if user attached zip then stop form submission

function onSubmit() {
    //Type appropriate comment here, and begin script below


    var countRequired = 1;
    if (window == null) {
        // portal
        if (this.document.getElementsByClassName('get-attachment').length != countRequired) {
            alert('You must add 1 attachment before submitting this request.');
            return false;
        }
    } else {
        // native view
        var length = $j("li.attachment_list_items").find("span").length;
        if (length != countRequired) {
            alert('You must add 1 attachment before submitting this request.');
            return false;
        }
    }

    var arr = [];

    if (window == null) {
        // portal
        var z = this.document.getElementsByClassName("get-attachment ng-binding ng-scope");
        var k;
        for (k = 0; k < z.length; k++) {
            var value = z[k].innerHTML;
            value = value.substring(0, value.indexOf('('));
            arr.push(value.trim());
        }
    } else {
        // native get all the file names
        $j("a.content_editable").each(function(index) {
            var val = $j(this).text();
            arr.push(val);
        });
    }

    var allowedExtension = '.pdf';
    var isAllowed = true;
    for (var i in arr) {
        if (arr[i].indexOf(allowedExtension) == -1) {
            isAllowed = false;
            break;
        }
    }

    if (!isAllowed) {
        g_form.addErrorMessage('Please add only pdf files');
        return false;
    }


}

Ensure Isolate Script = False for this client script to allow DOM
