How do I add a new method to Encore\Admin\Grid\Column ?

• Laravel Version: 8.12
• PHP Version: 8.0.28
• Laravel-admin: 1.8.16

Description:

I am trying to add a new column filter. To achieve this, I need to place a new method similar to "filter" that exists in "Encore\Admin\Grid\Column". Since this is part of a vendor package, I cannot edit it directly. Therefore, my plan is to rewrite this vendor class. I tried using the following code in "AdminServiceProvider". This is a new ServiceProvider I added under config/app.php to make this change.

public function boot() { Admin::booting(function () { $this->app->singleton(\Encore\Admin\Grid\Column::class, \App\Admin\Extensions\Override\Grid\Column::class); }); }

Here my try is to rewrite vendor class method "filter"

`<?php

namespace App\Admin\Extensions\Override\Grid;

use Encore\Admin\Grid\Column as OriginalColumn;

class Column extends OriginalColumn { /**

• Set column filter.
• @param mixed|null $builder
• @return $this */ public function filter($builder = null) { dd('sss'); return $this->addFilter(...func_get_args()); } }`

I do not see this change reflected. Could someone help me with rewriting this vendor class?

I need to keep the column filter open, like below

I did this by editing the vendor files.

1. Edited "Encore\Admin\Grid\Column" class by adding new method called "open_filter"

`/**

• Set column open filter.
• @param mixed|null $builder

• @return $this */ public function open_filter($builder = null) { return $this->addOpenFilter(...func_get_args()); }`

  2. Inside the trait "HasHeader", added "addOpenFilter" method

  `protected function addOpenFilter($type = null, $formal = null) { if (is_array($type)) { return $this->addHeader(new CheckOpenFilter($type)); }

  if (is_null($type)) {
      $type = 'equal';
  }
  
  if (in_array($type, ['equal', 'like', 'date', 'time', 'datetime'])) {
      return $this->addHeader(new InputOpenFilter($type));
  }
  
  if ($type === 'range') {
      if (is_null($formal)) {
          $formal = 'equal';
      }
  
      return $this->addHeader(new RangeOpenFilter($formal));
  }
  
  return $this;

  }`

  3. included CheckOpenFilter, InputOpenFilter and RangeOpenFilter classes to the folder. those actually a copy of InputFilter, CheckFilter and RangeFilter. The only change is below

  Updated the inline styling of ul dropdown-menu class element with below

  style="padding: 10px;box-shadow: 0 2px 3px 0 rgba(0,0,0,.2);left: -5px;border-radius: 0; display: block; position: relative;" display and position updated.

  Now, I achieved this by editing vendor files. However, this approach is not allowed and is generally considered a bad practice to meet this requirement. As I mentioned in my question, I was unable to achieve the same result using the rewrite method.

If anyone knows of a better approach to accomplish this without editing the vendor files, please advise.
