## Details
|
|
|
|
You can define a custom schema for the list in the `app.config.json` file and access it with the
|
|
`presetColumn` property as shown below:
|
|
|
|
```json
|
|
"adf-process-list": {
|
|
"presets": {
|
|
"customSchema": [
|
|
{
|
|
"key": "name",
|
|
"type": "text",
|
|
"title": "name",
|
|
"sortable": true
|
|
}],
|
|
"default": [
|
|
{
|
|
"key": "name",
|
|
"type": "text",
|
|
"title": "name",
|
|
"sortable": true
|
|
}],
|
|
}
|
|
}
|
|
```
|
|
|
|
```html
|
|
<adf-process-instance-list
|
|
[appId]="'1'"
|
|
[state]="'open'"
|
|
[presetColumn]="'customSchema'">
|
|
</adf-process-instance-list>
|
|
```
|
|
|
|
You can also define the schema in the HTML using the
|
|
[Data column component](../core/data-column.component.md). You can combine this with schema
|
|
information defined in `app.config.json` as in the example below:
|
|
|
|
```json
|
|
"adf-process-list": {
|
|
"presets": {
|
|
"customSchema": [
|
|
{
|
|
"key": "id",
|
|
"type": "text",
|
|
"title": "Id",
|
|
"sortable": true
|
|
}],
|
|
"default": [
|
|
{
|
|
"key": "name",
|
|
"type": "text",
|
|
"title": "name",
|
|
"sortable": true
|
|
}],
|
|
}
|
|
}
|
|
```
|
|
|
|
<!-- {% raw %} -->
|
|
|
|
```html
|
|
<adf-process-instance-list
|
|
[appId]="'1'"
|
|
[presetColumn]="'customSchema'">
|
|
<data-columns>
|
|
<data-column key="key" title="title" class="full-width name-column">
|
|
<ng-template let-entry="$implicit">
|
|
<div>{{getFullName(entry.row.obj.assignee)}}</div>
|
|
</ng-template>
|
|
</data-column>
|
|
</data-columns>
|
|
</adf-process-instance-list>
|
|
```
|
|
|
|
<!-- {% endraw %} -->
|
|
|
|
### Pagination strategy
|
|
|
|
The Process Instance List also supports pagination:
|
|
|
|
```html
|
|
<adf-process-instance-list
|
|
[appId]="'1'"
|
|
[page]="page"
|
|
[size]="size"
|
|
#processList>
|
|
</adf-process-instance-list>
|
|
<adf-pagination
|
|
*ngIf="processList"
|
|
[target]="processList"
|
|
[supportedPageSizes]="supportedPages"
|
|
#processListPagination>
|
|
</adf-pagination>
|
|
```
|
|
|
