### Usage

#### Options
##### 1. `status` 🔴

Status object to enable or disable ListView.

**Example:**
```
{
    enable: false,
    message: __('ListView is disabled.'),
    color: 'red'
}
```

##### 2. `query_fields`

List of additional fields to fetch but not display.

**Example:**
```
['is_approved', 'is_paid']
```

##### 3. `query_filters`

List of additional filters for the fetch query.

**Example:**
- Object:
```
{is_approved: 1, is_paid: 0}
```
- Array:
```
[
    ['is_approved', '=', 1],
    ['is_paid', '=', 0]
]
```

##### 4. `page_length`

Number of rows to display per page.
- Default: `20`
- Minimum: `20`

**Example:**
```
50
```

##### 5. `parser`

Function to modify the list data before display.

⚠️ *Important* ⚠️

If an error isn't caught inside the parser function, all data modification will be ignored and original data will be rendered automatically instead.

**Examples:**
```
function(data, render, error) {
    let names = [];
    data.forEach(function(row) {
        names.push(row.name);
    });
    frappe.db.get_list('Doctype', {
        fields: ['name', 'value'],
        filters: {
            name: ['in', names],
        }
    }).then(function(list) {
        list.forEach(function(vals) {
            data.forEach(function(row) {
                if (vals.name === row.name) {
                    row.value = vals.value;
                }
            });
        });
        // Render modified data
        render();
    }).catch(function(e) {
        console.error(e.message, e.stack);
        // Render original data instead
        error();
    });
}
```

##### 6. `set_row_background`

Function to set the row background color.

**CSS Colors & Keys:**

 <img src="https://github.com/kid1194/frappe-better-list-view/blob/main/images/row_bg.png?raw=true" alt="Frappe Better List View"/>

**Examples:**
```
function(row) {
 let cost = cint(row.cost);
 if (cost > 1000) return 'danger';
 if (cost > 800) return '#ffeeba';
 if (cost > 600) return 'rgb(190,229,235)';
 if (cost > 400) return 'rgba(190,229,235,1)';
 if (cost < 200) return 'hsla(133.7,41.2%,83.3%,1)';
}
```

#### Methods
##### 1. `toggle_status`

Method to enable or disable ListView on demand. It can be called from within `onload` event.

**Example:**
```
frappe.listview_settings['DocType'] = {
    onload: function(listview) {
        if (!frappe.user_roles.includes('Some Role')) {
            listview.toggle_status(false, __('ListView is disabled.'), 'red');

 return [__('Paid'), 'blue', 'is_paid,=,Yes|is_approved,=,Yes'];
 }
 if (doc.is_approved) {
 return [__('Approved'), 'green', 'is_paid,=,No|is_approved,=,Yes'];
