Inherit a widget in js odoo 16

Question

There is an edit that I made on the search more option, I need it to be shown all the time, in odoo 14, i made it by this code :

    odoo.define('customized_m2o_widget.Fields', function (require) {
    "use strict";

    var relational_fields = require('web.relational_fields');
    var FieldMany2One = relational_fields.FieldMany2One;

    FieldMany2One.include({
    _search: async function (searchValue = "") {
    const value = searchValue.trim();
    const domain = this.record.getDomain(this.recordParams);
    const context = Object.assign(
    this.record.getContext(this.recordParams),
    this.additionalContext
    );
    var values = await this._super.apply(this, arguments);

    if (this.limit >= values.length || this.limit < values.length) {
    values = this._manageSearchMore(values, value, domain, context);
    }

    return values;
    },
    })
    });

now I need to migrate to odoo 16, so anyone have a way to do it in the write syntax and semantic code to let it works again? thanks in advance

Try to patch the many2one_field widget and set the search limit to -1

Example:

/** @odoo-module **/

import {patch} from "@web/core/utils/patch";
import {Many2OneField} from "@web/views/fields/many2one/many2one_field";

patch(Many2OneField.prototype, "Many2OneField.SearchMore", {
    get Many2XAutocompleteProps() {
        return {
            ...this._super(...arguments),
            searchLimit: -1,
        };
    }
});

Add the following entry to the manifest file:

'assets': {
    'web.assets_backend': [
        'MODULE_NAME/static/src/js/many2one_search_more.js',
    ],
},

Update

Inherit relational_utils to override loadOptionsSource function

Example:

import {patch} from "@web/core/utils/patch";
import { Many2XAutocomplete } from "@web/views/fields/relational_utils"


patch(Many2XAutocomplete.prototype, "Many2XAutocomplete.SearchLimit", {

    async loadOptionsSource(request) {
        var options = this._super(request);
        return options;
    }
});
