pedro-cf opened a new issue, #67851:
URL: https://github.com/apache/airflow/issues/67851
### Under which category would you file this issue?
Airflow Core
### Apache Airflow version
3.2.2
### What happened and how to reproduce it?
When a DAG param has a long **name** (the key shown as the field label), the
Trigger DAG modal does not fit the label: text runs past the modal edge or
breaks the layout. Shorter names are fine; the problem is label length, not the
number of params.
**How to reproduce:**
1. Define a DAG with a param whose name is a long string.
2. Open Trigger DAG for that DAG in the AF3 UI.
3. The param label overflows the modal width.
**Example DAG:**
```
from airflow.sdk import Param, dag, task
@dag(
dag_id="trigger_long_param_name",
schedule=None,
params={
"lorem_ipsum_dolor_sit_amet_consectetur_adipiscing_elit_sed_do_eiusmod_tempor_incididunt_lorem_ipsum_dolor_sit_amet_consectetur_adipiscing_elit_sed_do_eiusmod_tempor_incididunt":
Param(
default=False,
type="boolean",
),
},
)
def trigger_long_param_name():
@task
def echo_params():
pass
echo_params()
trigger_long_param_name()
```
**Preview**:

/>
### What you think should happen instead?
The Trigger DAG modal should grow wider when the viewport has space, so
longer param names can be shown without clipping.
Only after a reasonable maximum width is reached (e.g. most of the screen)
should the UI apply a fallback: wrap the label, truncate with ellipsis plus
tooltip, or similar.
